JOSEPH LINNROTT, OF GALESBURG, ILLINOIS.

CORN-PLANTER.

SPECIFICATION-forming part of Letters Patent No. 277,495, dated May 15,1883.

Application tiled Jfuly 31, 1882. (No model.)

T0 all whom fit may concern:

Beit known that 1, Josera L1NNRoTT,a citizen of Sweden, residing atGalesburg, in the county of Knox and State ot' Illinois, have inventedcertain new and useful Improvements in Corn-Planters; and I do herebydeclare the followin g to be a full, clear, and exact description oftheinvention, such as will enable others skilled in the art to which it.appertains to make and use the same.

M y invention relates to corn-planters ot' the automatic check-rowclass; and it consists in constructions and combinations hereinafterdescribed, and set forth in the claims hereto annexed.

In the accompanying drawings, which illustrate my invention, Figure l isa top plan. Fig. 2 is a side elevation of a supporting-wheel andseed-dropping device, partly in section. Fig. 3 is a sectional elevationof the seed-box, supporting-wheel, seed-cup wheel, and seedretainingwheel in linea'xin Fig. 2. Figa is an enlarged perspective of a segmentof the seed-cup wheel. Fig. 5 is an enlarged sectional elevation oftheseed-dropping devices. Fig. 6 is an enl'arged side elevation, partly insection.

teferring to the drawings by letters, the same letter indicating thesame part in the different gures, letter A represents the frame of acorn-planter, which may be constructed in any ordinary well-known ordesired manner; A', the shaft, loosely journaled in the frame.

B are the supporting-wheels, loosely journaled upon their shaft; C, thedraft-pole, and D the drivers seat.

E are the seed-boxes, supported by any suitl able bars, e, on the frameA.

Ou each side of the frame A, and immediately beneath each seed-box, anannular plate or ring, F, is supported by rigid attachment to the frameA. The ring F has an enlarged opening,f,iu its upper side,immediatelyunder the seed-box, and another similar open`ing,f, adjacent, and has anopening, f, in its lower side, directly beneath the opening f, and anopening, f, adjacent to the openingf", and directly beneath theopeningj". Acover or cap, G, is adapted to cover either openingff, asrequired, and for purposes hereinafter explained.

Interior to and fitting snuglywithin the fixed annularplateF is a ringor Wheel, H, which may be a disk, or may be formed, as shown, of a rim,spokes, and hub. The wheels H are fixed on the axle ot' the wheels B,and each has a ratchet-wheel, H', fixed thereto, or tixed to the axle,with which a pawl, b, ou its adjacent wheel B engages when the wheel Brotates forward, and thus gives motion to the wheels H. Either wheel Bmay turn backward in turning the planter, and for other purposes,without moving the wheels H. Arms b' project from the axle, which may betaken hold of by the driver to rotate the axle, and thereby rotate ormove the wheels H, as required, in starting in at the ends of rows, orat other times where necessary to align the dropping devices with thetransverse rows of dropped seed. The wheel H has a circumferentialgroove, h, iu its exterior surface, immediately beneath the openiugf,and coincident with the openingj'". When the cap G is placed over theopening/'Q the seed in the box E will pass through the openingfand in'tothe groove lz., and will be retained therein by the ring F, and passingdownward by the rotation ofthe wheel H will be discharged through theopening f" into the ground, and in what is usually known as drilledplanting.7

.l l I are enlargements in the rim of the wheel H, and each enlargementcontains a pocket or seed-cup, t', in its exterior surface. The poehetst', in the rotation ofthe wheel H, pass beneath and coincident with theopening", and are thereby filled with seed, each in a quantity`sufficient for a hill7 of corn. seed in a pocket t' is retained thereinby the fixed ring F until it reaches the opening f, where it isdischarged near the surface of the ground. The distance between thepockets yi will ofcourse regulate the distance between the hills ortransverse rows ot'corn, andthe check-row planting be e'ected in theevident manner. While using the machine forcheckrow planting, as lastdescribed, the plate G is placed over the openingf.

J is a furrow-opener projecting downwardly from the front end of a bar,K, in front ofthe ring F.

L is a seed-covering share projecting downwardly from the rear end ofthebar K, in rear ofthe ring F. The bar K is carried in a slotted pendant,M, and may be raised and lowered Each. charge of IOO by means of a bentlever, N, and rods n in the evident manner.

I am aware that an annular plate or ring having openings coinciding withthe groovev and seed-cups of awheel inclosed with the annular plate orring, so that the seed passing through the upper openings in the saidplate or ring to the inclosed wheelwill be carried by the latter to thelower openings of said plate or ring and dropped, is old, and to that Imake no claim; vbut What I claim as new, and desire to secure by LettersIatent, is

l. In a corn-planter, the combination ot' a shaft loosely journaled inthe frame, and having a Wheel, H, and a ratchet-wheel, H', fixedthereon, supporting-wheels B, loose upon the shaft, and having a pawl,b, which imparts motion to the shaft when in contact with Wheel H andthe wheelsB are moved, and an annular plate or ring, F, encircling thewheel H, and having openings lfor receiving and discharging corn fromthe seed-box E, and supported from the frame by the bars e, substan- Itially as and for the purpose set forth.

2. In a cornplanter, the combination of a shaft loosely journaled in theframe, and having lixed thereon a Wheel, H, provided With acircumferential groove, 7L, and seed-cups t', and a ratchet-Wheel, H',supporting-wheels B,1oose upon the shaft, and having a pawl,^b, whichimparts motion to the shaft when in contact with wheel H' and the WheelsB are moved, and an annular plate or ring, F, encircling the wheel H,and having openings f f coinciding, respectively, with said groove h,and seed-cups t', and discharge-openingsff at its lower side, andprovided with a valve, G, adjustable to either opening, substantially asand for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH LINNROTT.
